I am trying to upgrade my domain controller to Windows 2008 from Windows 2003. I stood up the new server and promoted it to a DC in the same domain and promoted it to a global catalog server. I also installed DNS and transferred the FSMO roles to the 2008 server. Everything seemed to be fine, Active Directory and DNS were replicating to the new server..
When I tried to demote the old server, I received a caution that there was no other Active Directory DC's in the forest. I then tried shutting off the old DC and all computers lost connection to the domain... I also noticed that when I bring up \\NEWDC my SYSVOL and NETLOGON shares are missing..
I have never had this problem on any other domain so I was hoping I could find answers here.. Any help would be greatly appreciated..
